Yeah I used Claude for most of the code, not gonna hide it. Game jams are where vibe coding actually makes sense, you don't build up tech debt in 72 hours. Would've developed half the features doing it "properly". Still, doesn't meant I prompted "make me a game" and did nothing else. F.e. ball and physics balancing took like a few hours. I've tried to make a feeling of the ball and paddle a little bit more footballish, but in some moment it became to feel too slow and undynamic, so I've finished with the numbers below:

Ball physics:
- RigidBody2D, linear_damp 0.18 for gradual slowdown
- Hit direction = vector from paddle center to ball center (normalized)
- If paddle is moving its velocity adds 25% influence to hit direction(just balanced it manually). So moving into the ball shifts the angle
- Paddle speed also adds 25% to ball speed
- Wall bounces have 0.88 factor (loses 12% speed per bounce)
- Max speed scales with combo: 2000 + combo * 10

Paddle physics:

  • CharacterBody2D, max speed 2200(Player) 2000(Bot)
  • Player follows mouse with 0.3 smoothing (for web jitter)

So you added 25% of the speed of the paddle to the ball. Godot give you paddle speed are did you have to track that yourself. So you change ball direction by taking the normal and adding 25 percent. I like the wall bounce damping. 

Two things:

1. Could you ever move the paddle so fast that the ball misses it between frames or did capping the speed stop that? Did you use _physics_process() or _process()

2. I have been a programmer for almost 50 years, I still use ChatGPT, Grok, Calude.ai and another tool that I can get my hands on. In the arena of programming you use every tool you can get. It is no different than watching a tutorial on YouTube, buying some course, or reading it in a book which is what I did when I started programming 50 years ago. People have this stigma about AI. To me it is just a command line where you type in questions and it looks it up for you. Don't ever forget, you are a coder and all this code being spewed out by AI still needs to be checked.

I really liked your game, you are an excellent coder and designer. Keep it up, you never know you might have the next hit game in your head right now!!

1. Both. I use:
func _process(_delta: float) -> void:
_visual_position = _visual_position.lerp(global_position, VISUAL_SMOOTH_FACTOR)
sprite.global_position = _visual_position

And for physics I use physics_process. That combination gives really smooth movement visually and catch slightest mouse movement changes at the same time.

2. Glad we're on the same page, really. AI balancing was a semi-manual machine learning and current version of evolving, super-smart npc took me like a one working day, I'm kinda impressed. Took me a whole week to do the same task on other game without some GPT. 

3. Thank you once again, I really appreciate your support. I'm dedicated to do more games, so stay tuned! Have a nice time of day you have :D
